Unset works, but if he's trying to do a search and remove in one function,
unset is a step removed from that criteria (missing the 'search' part).
Looking at the array functions, I see some potential.
# array_remove(array(1=>2,2=>3),2,true); // array (2=>3)
// Keep all but where values = 2
$new_array = array_diff(array(1=>2, 2=>3, 3=>4), array(2));
print_r($new_array);
# array_remove(array(1=>2,2=>3),2,false); // array (1=>2)
// Keeps only where values = 2
$new_array = array_intersect(array(1=>2, 2=>3, 3=>4), array(2));
print_r($new_array);
So keeping the same syntax you had:
function array_remove($array, $remove, $remove_value = true) {
$remove = array($remove);
if ($remove_value) {
return array_diff($array, $remove);
} else {
return array_intersect($array, $remove);
}
}
Not a single function but a simpler version of your function.
